Abstract
Description
Technical Field
[0001] This utility model relates to the field of printing technology, and in particular to a page drying device for book printing. Background Technology
[0002] The printing drying system is a crucial part of the printing process. Its function is to accelerate the curing of inks, coatings, or adhesives through physical or chemical means, ensuring that printed materials are quickly set and achieve the required performance. In book printing, the pages need to be dried before the next steps of binding and cutting, in order to prevent the ink from sticking together. Existing printing drying methods include UV drying (ultraviolet light curing), infrared drying (IR drying), and hot air drying, among which UV drying is the most commonly used. Its advantages are no solvent evaporation, fast drying speed (millisecond level), and suitability for high-precision printing.
[0003] However, existing UV drying equipment has the following drawbacks: UV lamps generate a lot of heat during operation, which can easily cause the UV lamp module temperature to rise. Excessive UV lamp module temperature can lead to: changes in the output wavelength of the UV lamp, reduced matching efficiency with the photoinitiator, affecting the curing effect; and the rapid evaporation of solvent-based inks or coatings at high temperatures, forming bubbles or pinholes, increasing the scrap rate. It can also cause paper to yellow and become brittle. Therefore, after a period of use, the UV lamp module is often turned off for a period to cool down before being turned back on, severely reducing drying efficiency. Furthermore, operators sometimes forget to turn off the cooling, leading to paper spoilage. Utility Model Content
[0004] In view of the above situation and in order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a book page drying device for book printing, which effectively solves the problem that the existing drying devices cannot cool down independently.
[0005] The technical solution is as follows: This utility model includes two support plates arranged opposite each other, with pulleys rotatably connected to the left and right sides of the two support plates respectively. The two pulleys are connected by a transmission belt. An mounting plate is provided on the upper part of the support plates, and a drying hood is provided on the two mounting plates. Multiple UV lamps are provided on the upper side wall of the drying hood. Material conveying troughs are provided on the left and right sides of the lower end of the drying hood respectively. A water pump is provided at the rear end of the drying hood. A cooling pipe is provided on the outer surface of the drying hood. The cooling pipe is filled with coolant and has multiple evenly distributed heat dissipation fins. One end of the water pump is connected to the beginning of the cooling pipe through an inlet pipe, and the other end of the water pump is connected to the end of the cooling pipe through an outlet pipe. An air inlet is provided at the front end of the drying hood, and a rotatable fan is provided inside the air inlet.
[0006] Preferably, the front end of the drying hood is equipped with a cooling motor, and the output shaft of the cooling motor is coaxially and fixedly connected to the blower fan.
[0007] Preferably, the drying hood has multiple heat dissipation holes at its rear end.
[0008] Preferably, the front end of the front support plate is provided with a drive motor, and the output shaft of the drive motor is coaxially and fixedly connected to the pulley on the left side.
[0009] Preferably, the cooling pipes are arranged in a serpentine reciprocating pattern, and the distance between adjacent pipe sections is 5-8 cm.
[0010] Preferably, the heat dissipation fins are made of aluminum in a corrugated shape, and the spacing between the heat dissipation fins is 2-3 mm.
[0011] Preferably, the support plate is provided with legs on the left and right sides at its lower end.
[0012] Compared with the prior art, the beneficial effects of this utility model are: it can irradiate the printed pages with UV light to cure and dry the printing ink, prevent ink from sticking together, and cool the UV lamp tube to prevent the heat generated from accumulating and causing the temperature inside the drying chamber to be too high, thus avoiding yellowing and embrittlement of the paper due to excessive temperature.

Therefore, this utility model is not limited to the implementations of the base model disclosed below.
[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0022] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.
[0023] Depend on Figures 1 to 5 The device includes two support plates 1 arranged opposite each other, with pulleys 2 rotatably connected to the left and right sides of the two support plates 1 respectively, and the two pulleys 2 connected by a transmission belt 3. The upper end of the support plate 1 is provided with a mounting plate 4, and a drying hood 5 is provided on the two mounting plates 4. Multiple UV lamps 6 are provided on the upper side wall of the drying hood 5. Material conveying troughs 7 are opened on the left and right sides of the lower end of the drying hood 5 respectively. A water pump 8 is provided at the rear end of the drying hood 5. A cooling pipe 9 is provided on the outer surface of the drying hood 5. The cooling pipe 9 is filled with coolant and has multiple evenly distributed heat dissipation fins 10. One end of the water pump 8 is connected to the first end of the cooling pipe 9 through a water inlet pipe 11, and the other end of the water pump 8 is connected to the tail end of the cooling pipe 9 through a water outlet pipe 12. An air inlet is provided at the front end of the drying hood 5, and a rotatable fan 13 is provided in the air inlet.
[0024] To facilitate the rotation of the blower fan 13, a cooling motor 14 is provided at the front end of the drying hood 5, and the output shaft of the cooling motor 14 is coaxially and fixedly connected to the blower fan 13.
[0025] To facilitate heat dissipation, the rear end of the drying hood 5 is provided with multiple heat dissipation holes 15.
[0026] To facilitate the rotation of pulley 2, a drive motor 16 is provided at the front end of the front support plate 1, and the output shaft of the drive motor 16 is coaxially and fixedly connected to the pulley 2 on the left side.
[0027] For ease of use, the cooling pipes 9 are arranged in a serpentine reciprocating pattern, and the distance between adjacent pipe sections is 5-8cm.
[0028] To facilitate heat dissipation, the heat dissipation fins 10 are made of aluminum in a wavy shape, and the spacing between the heat dissipation fins 10 is 2-3mm.
[0029] For ease of support, the support plate 1 is provided with legs on the left and right sides at its lower end.
[0030] In use, the drive motor 16 is first turned on, which drives the pulley 2 on the left to rotate, thereby moving the conveyor belt 3. At the same time, the cooling motor 14 and the UV lamp 6 are turned on. Then, the printed pages are fed onto the conveyor belt 3. The conveyor belt 3 carries the pages through the feed chute 7 on the left into the drying hood 5. At this time, the UV lamp 6 irradiates the pages, curing the ink printed on the pages and achieving the purpose of drying. The dried pages continue to be conveyed by the conveyor belt 3 and output from the feed chute 7 on the right. The pages are continuously fed onto the conveyor belt 3, thereby achieving continuous drying.
[0031] At the same time, the water pump 8 is turned on to make the coolant circulate in the cooling pipe 9. The heat generated by the UV lamp 6 is transferred to the cooling pipe 9 and then to the coolant therein, thereby preventing the temperature from rising due to heat accumulation. The heat in the coolant is dissipated through the heat dissipation fins 10, thereby lowering the temperature of the coolant and continuing to absorb the heat generated by the UV lamp 6. At the same time, the water pump 8 makes the coolant circulate repeatedly to prevent heat accumulation.
[0032] At the same time, the cooling motor 14 drives the fan 13 to rotate, blowing out the heat generated by the UV lamp 6 through the heat dissipation hole 15 to prevent the temperature inside the drying hood 5 from rising. After drying is completed, the cooling motor 14, UV lamp 6 and drive motor 16 can be turned off.
[0033] Compared with the prior art, the beneficial effects of this utility model are as follows: the drying hood, cooling pipe, and fan can be used to irradiate the printed pages with UV light, thereby curing and drying the printing ink and preventing ink sticking. At the same time, it can cool the UV lamp tube to prevent the heat generated from accumulating and causing the temperature inside the drying hood to be too high, thus avoiding yellowing and embrittlement of the paper due to excessive temperature. The combination of coolant cooling and fan cooling achieves the best cooling effect. This structure is simple, novel in design, easy to use, and highly practical.
[0034] It should be noted that, depending on the implementation needs, the various components described in the embodiments of this utility model can be split into more components, or two or more components or parts of components can be combined into new components to achieve the purpose of the embodiments of this utility model.
[0035] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
